POETV is truly the only place where Bart The General and Quantum Mechanics can intercede with any sort of regularity.

It sounds like the sort of thing that they would use Quantum Mechanics to research.

Oh, Hai-senberg uncertainty principle!

This is what a description of a subject from someone who *really knows what they are talking about* sounds like. Its sounds simple.

It IS simple, all you need is a ready supply of helium-3 and helium-4, and the ability to cool them until they become superfluids.

This is the most respect I've ever had for someone with a soul patch.

Desperately needs the "SCIENCE HAIR!" tag.

I was interested but the stars are for 9:00.

I don't know much about quantum physics or anything so hopefully this isn't a stupid question, but is this more efficient or useful than laser cooling?
StanleyPain - 2014-09-22
Oh wait nevermind.. I missed how he mentioned it was cooling an antenna. So yes, it is far more efficient for this as laser cooling can only cool atom-sized things pretty much.

The implications of combining this with nanotubes boggles the mind.
fluffy - 2014-09-23
Would it work in a nanotube context? My intuition (which is probably wrong) is that effusion wouldn't happen very effectively inside a nanotube, and it's the intermixing that makes this so effective in the first place. So it doesn't seem like it would work at all, and that it wouldn't be any more efficient if it did.

For that matter, does liquid helium even stay inside a nanotube? Wouldn't it just tunnel out? I guess a nanotube bundle could be kept inside a thick metal tube to prevent that but then I'm back to not seeing the advantage of nanotubes.

How many angels could dance on the head of a nanotube?

"giving a serious reply to a dumb troll." could be poetv's motto

So anyone know what happens to the recirculating helium when it returns to the H3 layer? He skipped that part.

Adds heat back into the system or what?

There are many new ways physicists are doing this, and I guess they are competing for the best one. A friend of my researching in quantum computing cooled beryllium ions with finely tuned lasers bouncing off eachother. I can't even begin to wrap my head around it.
